Rapidly detecting disorder in rhythmic biological signals: A spectral entropy measure to identify cardiac arrhythmias [PDF]

Phys. Rev. E 79, 011915 (2009), 2008
We consider the use of a running measure of power spectrum disorder to distinguish between the normal sinus rhythm of the heart and two forms of cardiac arrhythmia: atrial fibrillation and atrial flutter. This spectral entropy measure is motivated by characteristic differences in the spectra of beat timings during the three rhythms.

Clinical implications of left atrial changes after optimization of medical therapy in patients with heart failure

European Journal of Heart Failure, Volume 24, Issue 11, Page 2131-2139, November 2022., 2022
Among patients with new‐onset or worsening heart failure (HF) undergoing optimization of HF medical therapy, dose up‐titration of angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker (ACEi/ARB) therapy was associated with lower likelihood of left atrial adverse remodelling (LAAR).

Arrhythmia Classification from the Abductive Interpretation of Short Single-Lead ECG Records [PDF]

Proceedings of the 2017 Computing in cardiology conference (CinC) (pp. 1-4). IEEE, 2017
In this work we propose a new method for the rhythm classification of short single-lead ECG records, using a set of high-level and clinically meaningful features provided by the abductive interpretation of the records. These features include morphological and rhythm-related features that are used to build two classifiers: one that evaluates the record ...

Slow uniform electrical activation during sinus rhythm is an indicator of reentrant VT isthmus location and orientation in an experimental model of myocardial infarction.

, 2020
BACKGROUND: To validate the predictability of reentrant circuit isthmus locations without ventricular tachycardia (VT) induction during high-definition mapping, we used computer methods to analyse sinus rhythm activation in experiments where isthmus ...

Atrial amyloidosis: mechanisms and clinical manifestations

European Journal of Heart Failure, Volume 24, Issue 11, Page 2019-2028, November 2022., 2022
Atrial amyloidosis: pathophysiology and clinical manifestations. Atrial amyloidosis can manifest as part of a systemic disorder (as in amyloid light‐chain [AL] or transthyretin [ATTR] amyloidosis), or be isolated (in the form due to atrial natriuretic type [ANP] accumulation); this last form is often associated with permanent or persistent atrial ...
